What is the process by which scientists match sedimentary strata to other rocks of different ages?
Its position in the stratigraphic column, particularly if there are any index fossils.
if that fails, then radiometric dating techniques may be appropriate. There are a wide variety of radioisotopes to be used ranging from 14C (5700 years half life) through K-Ar, and to the various uranium series.
What else can I help you with?
What are the bands of different colored or structured materials in some sedimentary rocks called?
The different bands in sedimentary formations are called strata.
Sedimentary deposits built into relatively regular layers are known as?
Strata.
What are the layers found in sedimentary rocks called?
The layers found in sedimentary rocks are called strata. These are horizontal layers of sediment that have been deposited over time and then compacted and cemented together to form rock. Each layer represents a different time period in Earth's history.
Which type of rock forms in layers which are called strata?
Sedimentary rock forms in layers called strata. These layers are created when sediments such as sand, mud, and organic material are deposited over time and compressed together. Examples of sedimentary rocks include sandstone, limestone, and shale.
What law suggests that older rock strata are at the bottom and younger rock strata are at the top?
The law that suggests that older rock strata are at the bottom and younger rock strata are at the top is the law of superposition. This principle states that in an undisturbed sequence of sedimentary rocks, the oldest rocks will be at the bottom and the youngest at the top due to the natural layering process over time.
What refers to the investigative process by which geologists identify and match sedimentary strata and other rocks of the same ages in different areas?
The process is called stratigraphic correlation, where geologists compare the layers of rock (strata) in different locations to determine if they are the same age and have similar characteristics. This helps in understanding the geological history of an area and reconstructing past environments.

Strata.
What is the difference between strata and stratification?
Strata refers to distinct layers or divisions within a rock formation or other material. Stratification refers to the process of arranging or forming these layers. In essence, strata are the actual layers, while stratification is the process of layering.
Where can strata can be found sedimentary rock or igneous rock?
Strata can be found in sedimentary rocks, which form in layers over time as sediments accumulate and compact. Igneous rocks, which form from molten magma cooling and solidifying, do not typically have distinct layers or strata.
What are Layers of sedimentary rock referd to as?
Strata

What are layers of sedimentary rock called?
Strata (singular: stratum)
What are the the layers of sandstone?
The layers of any sedimentary rock are called strata.

What features tell you how a sedimentary rocked is layered?
Sedimentary rocks are often deposited in layers as strata. The feature that tells how a sedimentary rock is layered is called the bedding.
